IMHO stay away from the 7,100K bulbs, these are "blue" but not as good as the 03 actinics. I have this same lighting system above my 29G (just installed two weeks ago). I have 2 x 10K and 2 x 03 actinics. The bonus of this setup is that you can have the actinics on one ballast and the 10K's on the other. You can then place each on a seperate timer to allow for the actinics to fire first and shut off last (Dawn & Dusk effect). This also keeps your fish from becoming freaked by going from complete darkness to 220 watts in an instant, since PC's are instant on.
As far as SPS, if water parameters are peak, and circulation is good, I would think you could get away with some hardier specimens. SPS doing well under PC only is not unheard of... sucess depends upon great water and good bulbs... the Hellolights bulbs seems to be similiar to the Phillips I owned previously (Custom Sealife). Once the need replaced I'll be using Corallife replacements or CS if I can find them still.
